yes it will bolt straight up but you may want to consider a stronger clutch and pressure plate and realise eventually that the engine could destroy the box.

the ratios will either be 3.7 or 3.9 more than likely it will be a 3.9 as it is dual range. the easiest way to find out is to get the boxes serial number which is on the passenger side near the bellhousing join.

then google the string of letters and numbers

thanx,so is there a stronger dual range box i can get??

the dual range box that is in a GT turbo forester

Just take it easy in 1st as it's a bit thinner than the rest of the gears, otherwise they are the same strength & size. I've got a 92 d/r box in mine & it was 3.9 but now 4.44.

Sorry no there isn't but like Tom (d_generate) says.. just don't drive it like a race car and you'll be fine.

GTs have single range

Yeah.. and maybe change to L.Series low range

so none of the turbo foresters have a dual range box ?

unless they are installed after market ?

I had one of these delivered for $480, took a week to get here, fits great & works well, to go to 4.44 crown wheel & pinion in the d/r box you need to modify the shape if the pinion? (the big one) a bit so it doesn't grab on the opposite gears then find a WRX viscous rear diff preferably 4.44 so it drops straight in and that should be the cheapest way and enough to get you going provided you can do most of the work yourself. A 12kg center diff would be nice too but pretty hard to find.

$456 delivered now, ignore the 02 - 06, they'll fit any Lib, Legacy 89 onward box.

Not in factory fitted cars but so many people modify them.. I'm sure there is plenty around now They're like Carbied EJs.. every man and his dog wants one now

"Grab the opposite gears" - its the crown wheel that gets shaved down to allow it to clear the low range gears, typically done when the L series low range is installed in 4.11 and 4.44 EJ gearboxes...

And I'm pretty sure to find the 4.44 ratio diff you'll have to find either a foz box or a turbo box and use the ring and pinion gears from this. If you find the correct speedo gear you can also keep your speedo true I believe.

The rear LSD from a WRX should bolt straight in if its an R160 - if you get the R180 it won't work... Easiest way to make it fit is swap the diff centres - ScoobyRoo has done a write up about this as he recently busted a rear diff and had to swap the centre to retain the rear LSD. This issue is that the WRX rear diff might have the male drive shaft input to the diff rather than the stub axles on the diff.

Hope this helps.

Cheers

am i right in thinking i should just bolt complete foz box in??

The Foz box will fit straight in but just make sure you have the matching rear diff and grab all the cables, shifter, etc..
